Just bought this truck out of Colorado. I got a pretty good price on it and honestly just wanted a project truck. Truck came out of a ranch and i don't think it every saw the road. 2000 Ford F450 Crew cab long bed(flat bed) manual trans. The underside is so clean there isnt even a spot on the doors.

When it got here it had some trouble starting. It would fire up just smoked a lot and once warm it would clear right up. I rebuilt injectors once before so i decided to do it again. After they were done and installed it still didn't go right. I figured i would do it right this time and replace them.

So i bought new injectors, Turbo PED delete, new exhaust housing, up pipe gaskets, AIH delete and glow plugs.

The truck runs great when warm. I threw a pallet of salt on it and drove it for about 100 miles last night. I notice a little smoke when driving around (blue/White). When I start it up it smokes a little more then normal. Once i get 5 min down the road it clears right up though. The truck has a long start but still fires over without any trouble. It was around 18 here this morning and it started on the first key cycle even though it took at bit to turn over.

Under load it studders in 4th gear at around 2400-2500 RPM. I was thinking fuel pressure or oil?

Looking for some guidance here. I am more worried about the blue/white smoke on start up as i thought injectors would clear that up. I was thinking some how oil fuel was getting into the cylinders but with the new o rings on the new injectors i dot know how that's possible. Antifreeze looks good and the truck does not use any oil.

 

Here is a video of the blow by...

Can't see the video for some reason.

Where did you get the injectors from? How many miles since the injector swap?

 

Sorry I will try and fix the video when j get home. Right now about 107miles on New injectors. Just took along trip last night to try and work out the air.

 

Hopefully this works -

Turbo bushing can put oil in there and make it smoke good. A hot tune can do it, unless you're sure the PCM was never re-programmed. Fresh injectors didn't prevent problems for me - I didn't use proper torque procedures and they all worked loose. Smoke, knock, and cup damage ensued.

 

Looks excessive to me since it's pushing up the oil cap. You should do a compression test and go from there.

 

I agree. While the cap doesn't pop way up, that's a lot more blowby than Stinky has (300K miles), even with the EBPV closed at high idle. Stinky's oil cap can stay there without aid. The blowby might be shoving more oil vapors into the turbo, you could have oil coming in from valve guides or the bottom, or an injector could have worked loose already (that last one is doubtful).

 

yea I'm going to try a compression test this weekend. Its weird the smoke clears up for the most part on driving. it smokes like crazy when you first start it up, then after about 5 min it clears up. i must not have tightened the dog house down all the way after the injector install and the blow by coming out of the crank case was so bad it was rolling out of the edges of the hood.....i am leaning towards low compression but the thing has great power. here is a picture of the intake

 

Long time no see Phillip, hope things are going well.

Looks like you will have a compression issue, unfortunately, too much blowby.

 

Thanks! Glad to be back, the 6.7 was nothing but trouble and they wouldn't honor warranty.

I guess ill end up pulling the heads next weekend and replace the rings. Anyone have a good write up or link for these?

 

I have another thread open about the parts that i am ordering for the rebuild...but i was curious to see what you guys thought about this.

If the previous owner used ether on this thing, wouldnt that harm not only the rings but the exhaust valves? I am worried that this isnt a ring problem but a valve problem. It has low compression but cant a bad valve emulate the same thing?

 

Many folks that have manual tranny PSD's have had similar smokey cold starts. One that comes to mind is MontanaSteve on this forum. Installed Swamps 175/146 injectors & smokes a lot during cold starts just like it did with stock inj's. Then clears up when warmed up. It could just be in the tuning(timing tables). Which injectors did you use?

 

I used stock remans. This thing has very bad blow by im leaning more towards rings or valves. i just dont know which one

 

I hear ya Phil, but two of your comments above are exactly what other manual Trans folks are seeing.

Excessive cold start smoking that clears up after oil temps warm up.

No loss of power.

I'll e-mail Steve and see if he chimes in.

Did you ever get a chance to run a compression test?
